This example shows to configure like the environment below. | +------------------+ | +-----------------+ | [ Control Node ] |10.0.0.30 | 10.0.0.50| [ Proxy Node ] | | Keystone |-----------+-----------| | +------------------+ | +-----------------+ +----------------+ | 10.0.0.20| [ ClientPC ] | +---------------------------+--------------------------+-------------| | | | | +----------------+ |10.0.0.71 |10.0.0.72 |10.0.0.73 +-------+----------+ +--------+---------+ +--------+---------+ | [Storage Node#1] | | [Storage Node#2] | | [Storage Node#3] | | |-------| |-------| | +------------------+ +------------------+ +------------------+ |
[1] | Add a user for using Swift on Keystone Control Node. By the way, if you'd like to use Swift Quickly, it's unnecessarry to add a new user, it's posibble to use with existing admin or swift user on Keystone. |

[2] | Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first. |
root@client:~# apt-get -y install python-keystoneclient python-swiftclient
|
[3] | Load environment variables first. ( it's just the value for a user added in [1] ) |
root@client:~#
vi ~/keystonerc_swift
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=swiftservice export OS_USERNAME=user01 export OS_PASSWORD=userpassword export OS_AUTH_URL=http://10.0.0.30:35357/v3 export OS_IDENTITY_API_VERSION=3 export PS1='[\u@\h \W(swift)]\$ '

[4] | Create a Container for saving files. |
root@client ~(swift)# swift post test_container root@client ~(swift)# swift list test_container # just created |
[5] | Upload a file on local to the Container. |
# upload test.txt root@client ~(swift)# swift upload test_container test.txt test.txt root@client ~(swift)# swift list test_container test.txt # just uploaded |
[6] | Download a file from Swift Storage to local. |

[7] | Delete a file on Swift Storage. |
root@client ~(swift)# swift delete test_container test.txt test.txt root@client ~(swift)# swift list test_container test2.txt # test.txt is just deleted |
[8] | Delete a Container on Swift Storage. |
root@client ~(swift)# swift delete test_container root@client ~(swift)# swift list # just deleted
